Recycling of construction waste

Recycling of construction waste is a process of construction waste waste. For example, in addition to the construction waste landfill, in developed countries, the use of construction waste as a raw material for the production of recycled aggregate, used for the production of concrete and brick. Researchers have pointed out that the whole body is a waste of construction waste, after effective development, China's construction waste utilization rate of up to 95% or more.

1. construction waste classification: mainly the construction waste can be used again in waste steel, metal, wood and other sorting and recycling.

2. construction waste recycled brick: solid clay brick as a kind of traditional building material can no longer meet the needs of the development of the times, the use of construction waste production of recycled brick, and other new building materials can not only meet the requirements of the market of building materials and environmental protection, also can consume a large amount of construction waste, such as production 1.5 billion standard bricks can consume construction waste more than 40 million tons, saving dumps garbage covers an area of 160 acres.

3. construction waste production of recycled aggregate: the use of construction waste to produce recycled aggregate is one of the main ways of recycling of construction waste in our country. Will building garbage after preliminary cleaning, sorting out the recycling of steel and wood, the brick, cement concrete block after crushing equipment broken into aggregates, through the vibration sieve grading, removing impurities, the formation of a certain particle size requirements of building materials, then according to the gradation design requirement in raw materials, adding cement and fly ash and other accessories, add some water after mixing into concrete, used for the production of different building products and road construction products. These products can replace common sandstone used for the building of roads and other infrastructure.
